Meat (Chicken?)
pricy AF. coop or migros sell 100gr for like 4-6CHF. If you shop in germany you can buy that much for a kg

Fruits (Apple, banana, peach, mango, strawberries, frozen berries in general)
if you buy apples from turkish stores you can get away with 1-2CHF per kg for apples.
Drinks (Mineral water, Cola, Fanta, Sprite, Juices, Ice Tea)
In supermarkets about 0.50CHF per 500ml for water still.

or you could just google migros, coop, aldi supermarkets and check their prices

I know you asked specifically about food, but as a student I imagine you'll soon have questions about other costs, such as housing, cell phones, insurance, etc. Here are some threads that I think cover the topic nicely, including links and examples of actual expenses. The first one is a bit old, but quite comprehensive and worth a look. The second is more recent:

First of all it depends on where you do your shopping. Meat can be relatively cheap in Denner, Lidl or Aldi but not always the best quality. (for a bit less than 4 chf you can have a package of marinated chicken wings, things like that)
Same for fruits, vegs and more or less for drinks - Lidl/Aldi can have lots of cheapo brands.

And btw, you got groaned by Richdog 3 times! This guy never ceases to amuse me...
Anyway, hope you'll be able to manage on a student budget.

If you go for reduced articles (in the evening), avoid beef and pork, shop at least once a week over the border, don't eat out, your budget for Food and beverage should end in around 300-350 srf( per month).

Richdog lives in a parallel universe. Rather than EF being a brand new website with barely any content like in the real world, over there it's been going for years and years and people have asked many questions on the cost of living. Oh and the regulars get bored of lazy people asking the same questions over and over.

Btw chicken breasts are CHF 16 a kilo in Lidl. The quality is fine. The fruit and veg selection can be eclectic, but the quality for the price is fine.

Evidently the Three Billy Goats Gruff must have cancelled their appointment. Either that or it was chucking out time at the pub.

Have you thought about going on coop.ch or the Migros online shop and checking prices of different items there?

Otherwise, tell you what, I'll go round my local Coop for you and tot up the cost of a weekly shop. And why do you want to waste money on mineral water? We do have tap water here you know!

Well, I did go to Coop.ch but I thought it was very expensive. I didn't know that Aldi and Lidl are located in Switzerland as well. And mostly people living there probably know some tips to save some money, like the suggestion with shopping in Germany.

Nut if you are serious with telling me how much your weekly shop costs, it would be really nice.
